Fizostigmin (eserin) je parasimpatomimetski alkaloid. On je reverzibilni inhibitor holinesteraze.

Ova supstanca je sintetisana 1935. Dostupna je pod imenima: Antilirium, Isopto Eserine, Eserin salicilat i Eserin sulfat.

Farmakologija uredi

Fizostigmin deluje tako što ometa metabolizam acetilholina. On je kovalentni (reverzibilni - veza se hidrolizuje) inhibitor acetilholinsteraze, enzima odgovornog za razlaganje acetilholina u sinaptičkim rascepima neuromuskularnih spojeva.^[6] On indirektno stimuliše nikotinske i muskarinske receptore.

Biosinteza uredi

Biosinteza fizostigmina je predložena počevši od triptaminske metilacije i postheterociklizacije katalisane nepoznatim enzimom:
